I know he's been in a few movies, but I'm surprised he hasn't been in more . Richard "Jaws" Kiel had a long acting career. Valuev is the same height approximately, bulkier, and scarier looking than Kiel was.
I always liked Sugar Niko Valuev, or, to his fans, SNV. I know he got some dodgy decisions, but he worked hard, won a belt, beat some good fighters, and in his spare time managed to be a poet, actor, and yeti hunter. A real Renaissance man.
